Door for sidewalks.



WILLIAM E. SNAMAN, or ALLEGHENY, i. ni\nisvi,viiiviii.

Doon Fonsiniawfanits,

To all whom it may concern:

Be it known that I, WILLIAM E. SNAMAN, a citizen of the United StatesOfAmerica, residing at Allegheny, in the` county of Alle,-

gheny and State of Pennsylvania, have invented certain new and usefulimprovements in Doors for Sidewalks, of which the following is aspeciiication, `reference being hadV thereinto the accompanying drawingThis invention relates to `doors for sidewalks, and the invention hasfor its object to provide an air and water proof door that will lieflush with the surfaces of fapavement or i,

sidewalk.

^ inexpensive dooigwhich will avoid un ue o bstructions or raisedsurfaces in a sidewalk,l said door ,being of a. novel construction,`

wherein prevention is made against leakage through crevices surroundingthe door edges.

ln this connection, my improved door is particularly design-ed to beused as a'scuttle door a manhole covering, ahatch way'covering or a trapdoor, -the door being constructed whereby it may be made air tight,water proof and free from all danger of injuryby ordinary use. To thisend, I have oo nstructed a novel door frame adapted to' be -located in asidewalk or pavement, the Iframe providing a gutter lthat can be easily"drained or cleaned, thus pifeventingwater, dirt and' in the sidewalk-ofstone, `concrete' or 'other' material.

The detail construction enteringiiito my invention will be hereinaftermore fully described vandthen specifically pointed out in the appendedclaims.-

'ofhinge wherein the door supported slightly above a sidewalk, v Fig. 8 isa similar view illustrating a door supported 'flush with a sidewalk, Fig. 9 is a V detail sectional view of a portion of a sidewalkillustrating the manner of anchoring a hinge therein, Fig. 1() is avdetail sectional view of two doors illustrating the manner iny which anentire sidewalk caribe constructed vof hinged sections.

kIn the accompanying drawing, 1 indicates a hatch way oi" chamberlocatedinv the side# walk 2, and coimtersunk in tlie'sidewalk 2v' is arectangular metallic frame 3 constructed of angle iron. Upon the frame 3within the sidewalk l arrange a rectangular gutter 4 which issi'ibstaiitially channel-shaped in 'cross section, the inner sides 5 ofsaid frames being of a less rdepth than ,the'outer sides The gutter 4 isprovided with a therefrom. Siiitably secured tothe inner sides -of thegutter are hinges 7 vided with gaskets 1() of a resilient material suchas rubbensaid gaskets resting upon the The meeting edge' inner sides ,5of ,the frame 3v and providing a said hinges carrying. doors'Sand 9adapted tofall inwardly.A l The underneath sides of the doors 8 and' 9arepr of the door 9 isl provided with adepending cliannel-shapedmetallic strip 11.

The strip 11 is adapted to -rec'eive an angle iron -14 carriedmb f theineetingedge of the door S and if desi'ra le a resilient strip 15 can belocated. in the bottom of the channel-shaped strip 11 to provide apositive. connection of Athe two Adoors and cushion thefdoorS in saidstrip. 'The ends of the vdoors 8 and 9 overlving the frame 3 will irmlysupport the meeting edges of the doors, thereby dispensing with theordinary bar commonly used for supporting the meetingedges. The novelmanner in 4which the. meeting edges are connected together preventstliedo'ors from saggingand gettiiigiout of alinement with the level ofthe pavement. The doors are rendered air tight by employing the gasket10 and the resilient strip 15, while the channel-shaped frame 3 ico'tends Within close proximity to the topoi y clearance l241: tor thehinged doors.

.drame 26, said ira-me having its horizontal -enter the passage way ggd,

and Vchannel-shaped strip prevents water om entering the passage way orchamber I w rich is normally closed by the doors S and 9.

lt will be observed that the horizontal i flange 16 of the frame 3projects beyond the frame 4, thus more biirmly anchoring the traine 3inthe side walk or pavement 2.

ln Fig. 2 oi the drawing, l have illustrated a slight modification of myinvention wherein l have dispensed with the channel-shaped trame fr andemployed a frame constructed of angle bars ,said bars having theirhorizontal flanges 18, protruding a suliicient distance into the sidewalk or pavement 2 to provide a firm anchorage. The sidewalk or pavement24 is recessed as at 19, -to clear the movement of the hinge 7. ln thisview, I still retain. the frame 3, but as illustrated inremainingiigures of the drawing, namely the Figs. 3 to 9 inclusive, l dispensewith said frame.' y mother modification ot' my invention 'is illustratedin. Fig. 4 of the drawings, where l provide the doors with angle irons20, having strips otresilient material- 2l adapted to engage the anglebars l?, the strips el: resilient material serving as weather strips.

in Fig. 5 of the drawing, l have illustrated another modificationwherein the frame 22 of the passage way or compartment l e);-

oi the sidewalk .2 and carries the hinges for supporting the doors. rlheframe 22 provided with. ordinary Z-bars 23, to `n'ovide ill slightmodiiication of this construction is illustrated. in Fig. 6 wherein theZ-bars are dispensed with and curved bars 25 used.

Fig. '7 ot the drawing, l have illustrated a passage way Aor chamberframe 26 having a horizontal flange 27, provided with a rib 28. Securedto the frame 26 is a-Yhinge 29, the member of'said hinge being securedto one of the doors, and constructed to clear the flange 27 when thedoor is swung open. TheV hinged edge of the door is grooved, as at 3l,to engage over 'the rib 28 when the door is closed, this form supportingthe door slightly above the level of the side walk orv pavement 2.

` In Fig. 8 of the drawing, I have illustrated practically the samehinge as applied to the flange 27 provided with a seat 32. ln thisconnection, the door 8- is supported on a level Hush. With the surfaceof the sidewalk or pavement. v

ln the above mentioned Figs. 7 and 8, the hinged members 30 areemploved. for sup- -ecting water, dirt and such -aterial that may orchamber of the avement or sidewalk 2. lnsome instances,- l

may entirely disperse with the hinged roem-i.

bers 30 and carried by the use the metallic gutters 30 in lieu thereof.I

A still further modification of' myinvention is illustrated in Fig. 9 ofthe drawing, wheein the sidewalk or pavement 2 is provided with a hinge33 having an anchorage 34 in the pavement or sidewalk, said pavement orsidewalk being' recessed as at 35, to clear the movement of the hingeddoor 8. The pavement or sidewalk 2 is provided with a resilient strip olmaterial 33, to provide an air tight and water proof connection betweenthe pavement or sidewalk 2 and the doors 8 and 9. portance to thismodiiication, owing to the fact that theframes are entirely dispensedwith., the hinges being embedded within the concrete construction of thepavement or sidewalk.

ln Fig. l() of the drawing, is shown a construction adapted forsidewalks and pavements wherein hinged doors or sections 8 and 9 areprovided with transparent plates or lights 36. The doors or sections 8and 9 are hinged in a beam 37 of the channel construction.

Thron hout the various constructions disclose vabove it will Abeobserved that l have devised novel doors that can be readily opened fromthe inside of a passage way or chamber, the doors and their supportingelements being particularlyT designed for concrete pavements andsidewalks.

Vhile l have herein described the construction illustrated in Fig. 1 asthe preferred form, it is obvious that I ma f use such forms as arepermissible by the scope of the appended claims.

Thecombination pavement, having a passage way or ch amber formed therein,of a metallic frame surrounding the edges of said passage way, ametallic channel-shaped frame supported upon said metallic frame andhaving its inner sides of less depth than its outer sides, doors hingedto the inner sides of said channel-shaped frame, gaskets carried by saiddoors and adapted to impinge the inner sides of said channel shapedframe, a channel-shaped strip meeting edge of one of said doors, anangle iron carried by the meeting edge of the other of said doors andadapted to enter said channel-shaped strip, and a drain pipe connectingwith said channelshaped trame.
